NAPP currently operates the Casselman Mine, an underground mine utilizing the room and pillar mining method.
The Casselman mine is an active mine in the Upper Freeport seam. This mine is a metallurgical coal operation on leased mineral property.
Production is scheduled for 255 days each year, which represents production on Monday through Friday. On each day, one production section is scheduled to produce coal on two shifts; the third shift is reserved for maintenance and mine conveyor belt and power moves. The sections are configured as regular sections with one continuous miner available for production on each section. Productivity is planned at the rate of 250 feet of advance per shift of operation.
Principal production equipment includes two continuous miners, four roof bolters, three shuttle cars, a continuous haulage system, and two scoops. Coal is extracted from the production face with the continuous miner and hauled to the mine conveyor in shuttle cars or via continuous haulage. At the conveyor belt, the coal is discharged onto a feeder breaker for transfer onto the conveyor. The conveyors carry the coal to the outside, where it is stacked on the ground to await truck transport to the preparation plant and load-out.
Expected annual production averages approximately 545,000 marketable tons.
